COMBINED HARROW, ROLLER, AND SCRAPER.

SPECIFICATION forming part of Letters Patent No. 277,029, dated May 8, 1883.

Application filed May 15, 1862. (No model.)

To all whom it may concern:

Be it known-thatl, JOSEPH HARTER, of Tiflin, in the county of Seneca and State of Ohio,have invented certain new and useful Im- 'prov-ements in a Combined Harrow, Roller, and

eonjointly or each may be used separately, as

desired; and it consists in the peculiar construction of the machine orimplement whereby itjs adapted to be used as above mentioned, as will be hereinafter fully set forth and claimed.

In the drawings, Figure 1 is a plan view of my machine as used as a combined harrow, roller, and scraper. Fig. 2 is a side elevation of the same; and Fig. 3 is a vertical section taken through Fig. 1, line a; as. Fig. 4 is a plan view of my machine with rollers detached and supporting-wheels substituted. Figs. 5 and 6 are side elevations of Fig. 4, showing the man ner of operating the supporting-wheels and the function they perform. Figs. 7, 8, 9, 10, and 11 are detached views of some of the parts of my machine, showing more clearly their construction.

This invention is an improvement on a patent for road-scrapers granted to me December 14, 1880, and numbered 235,431.

Now, by reference to Figs. 1 and 2 ofsaid'patent, and to Fig. 4 of the drawings forming part of this present application, it will be seen that the constructions of the two machines are very similar, the difference being that I now provide a more simpledevicefor raising or lowering the harrow from the ground-viz., two wheels, 0 O, are pivoted to the short arms of two levers, D D, which are in turn journaled on the bar B in such a manner that as the long arms of the levers D D are thrown back or forward which consists of two hooks, to a, with which the levers on gage, as shown in Fig. 6.. A brace, E, is secured at one end to the reach Hand at its opposite end to the outer and unsupported end of the scraper, thereby stiffening the latter and preventing it from springing. The reach H is also made to extendback to a considerable distance farther, so as to permit of the scraper G being set back far enough to admit of the use of rollers F F.

When it is so desired to use the rollers F F it is only necessary to remove the levers D D with their wheels 0 O, which is done by removing the nut from one end of the barB and drawingit (the bar) out. The barB is again replaced, the wheels 0 .C and leversD D being removed, as shown in Fig.1. Two side bars,[ I,

are now secured, one to each end of the bar 13',

by means of nuts. (Not shown.) Extending upward from the side bars, I 1 and also from the reach H are vertical guides, b I) I), through which the shaft J of the rolls F F passes.

Between the rolls F F is a lever, K, which is pivotally attached to a lug, 0, extending upward from the reach H, and is also journaled on the shaftJin such a manner that when the long arm of thelever K is depressed it will act to raise the harrow A and scraper G from the ground, when the 'roller may be operated alone.

Secured in the rear of the rollers F F to the ends of the side bars, I I, is the scraper G, which differs essen tially from the scraper shown and described in my former patent.

As now made my scraper-bar Gis provided with teeth, (1, which are preferably secured to said bar in the manner shown in Fig. 9, which will be readily understood from said figure. I also provide acurved piece, G ,'which is detachably attached to the outer end of the scraper, and is used for the purpose of cleaning or scraping gutters. V

Fig. 10 shows the manner of securing the scraper G-to the bar Gviz by passing the same over the teeth d and bolting the scraper thereon. Fig. ll shows my preferred manner of forming my harrow-teeth.

\Vhen the scraper G is detached from the teeth at on the bar G the said bar G andteeth d may be used as a'rake or harrow.

N N are gage-bars, which are pivotally secured to the harrow A, and ad j ustably secured by the blocks and links, as shown in Figs. 7 and 8, to the bar B so as to enter above or below the bar and adapt them to-be raised or lowered to gage the depth to which-the teeth of. the barrow A shall enter the ground. It desired, a platform, N, may extend between the said gage-pieces, as shown in Figs. 1 and 4.

The rolls F F may, if desired, be provided with teeth, as shown in the drawings, Fig; 1. The parts of my device not herein mentioned or fully set forth are described in my aforesaid :o patent, and hence I do not deem it necessary to further describe them in this mypresent application.

What I claim isf 1. The combination, with a scraper and har= r 5 row, of the transverse shaft B, levers D D,

pivoted thereto, the short ends of said levers having wheels 0 O jonrnaled therein, substan= tially-as set forth.

2. The combination, with a barrow and scraper, of"- the reach'H andthe brace E, the 20 latter connecting the reach and scraper, snbstantially as set forth. V

3. The combination, with a barrow and scraper combined as herein described, of the rollersF'F, substantially as shown and de- 25 scribed.

In testimony whereof I 'h'ave'signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH HARTER.
